Meijun water blasting machine type IIII wet negative pressure water blasting equipment is suitable for recycling sand in the base of the blasting room.
Our company has been specialized in making sandblasting machines for more than ten years, with excellent technology and good machine quality.
Water blasting machine MG-FSP7500 is a kind of sand blasting equipment that complies with national standards and environmental protection standards. Compared with dry open type blasting machines, its characteristics are: water blasting, liquid blasting, and sand blasting. Automatic dust collection without dust discharge, sandblasting by one person or multiple persons.
Negative pressure water blasting machine uses:
Using net compressed air, spray (such as quartz sand, white corundum, ceramic sand, brown corundum, cast steel sand, river sand, etc.) strongly on the surface of metal workpieces, and grind off the burrs, scale, rust, and product on the surface of the workpiece. The process of surface defects such as charcoal, welding slag, molding sand, residual salt, old paint film, and dirt is called sandblasting.
Sand blasting is often used for surface cleaning of workpieces, such as removing residual sand and high carbon-containing layers on the surface of castings, and welding seams of weldments to eliminate rust and scale. Derusting generally uses sandblasting and pickling. The latter makes it easy for hydrogen to penetrate the inside of steel parts, increasing internal stress and reducing plasticity, while sandblasting and rust removal does not produce hydrogen embrittlement. Whether it is high-carbon steel, high-strength steel, or elastic parts, brass parts, stainless steel parts, and aluminum parts after sand blasting into the next process, the binding force of the plating or oxide layer can be improved. Co-construction of hard chrome plating and coatings is commonly used for sandblasting to clean the surface, and machine accessories and measuring tools are mostly sandblasted before matting with white chrome plating. Sand blasting is one of the best methods of surface pretreatment. Not only can it completely remove the oxide scale, rust, old paint film, oil stains and other impurities on the metal surface, so that the metal surface is exposed to a uniform metallic nature, but it can also obtain a certain roughness on the metal surface to obtain a uniform roughness Surface, and turn machining stress into pressure, improve the bonding force between the anticorrosive layer and the base metal, and the corrosion resistance of the metal itself. Commonly used for painting, thermal spraying and roughening of plastics. In addition to sandblasting, surface roughening methods include car thread method, knurling method, and electric spark drawing method.
Sand blasting is divided into two types, dry spraying and wet spraying. Abrasives for wet spraying are mixed with water to form a mortar. In order to prevent metal rusting, corrosion inhibitors need to be added to the water. The dry spraying efficiency is high, the processing surface is rough, the dust is large, and the abrasive is broken. The wet spraying has little environmental pollution, and it has a certain decorative and protective effect on the surface. It is often used for fine processing.
